To uZZ whmn it Hwy concern.-

Be it known that I, AUDY A. LOWRY, a citizen of the United States, residing at Anna, in the county of Union and State of Illinois, have invented a new and useful Threshing-Machine, of which the following is a specification.

This invention relates to self -propelling threshing-machines; and it has for its object to provide certain improvements within the to scope of the device which shall possess superior advantages in point of simplicity, durability, and general efliciency.

\Vith these ends in view the invention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a threshing-machine con structed in accordance with the principles of my invention. Fig. 2 is a longitudinal sectional view in detail, showing the construction of the casing of the chatting fan or blower, its relation to the shoe which carries the chaff- 2 5 ing-riddle, and also showing the construction of the conveyors to deliver the grain from the machine and discharge the same into sacks or other receptacles. Fig. 3 is a vertical transverse sectional view taken 011 a plane indicated by the line Z) l) in Fig.

My invention has special reference to that class of threshing machines which are equipped with an engine which may be used for the purpose of transporting the thresh- 3 5 ing-machine from one place to another by connecting suitable tractiongearing, which forms part of the machine, with the driveshaft of the engine, and which also when the machine has reached the scene of operation 0 may be utilized for driving the threshing mechanism. These parts of the device are not intended to be claimed in the present application and have only been partly shown in Fig. 1 of the drawings, which has been introduced only for the purpose of showing certain parts relating to my present invention. The latter may be described as consisting, essentially, in the improved construction of the casing of the chatting fan or blower in its relation to the shoe which carries the chaffing riddle and in the construction of certain conveyors whereby the cleaned grain is discharged from the machine into suitable receptacles.

Referring now to the drawings, 1 designates 5 5 the supporting-casing of the machine, which is mounted upon front wheels 2 and rear wheels 3, the latter constituting the tractionwheels. A

The general construction of the threshingmachine is well understood, it differing in no essential particular from threshing machinery of ordinary construction, being provided with a cylinder, of which 62 designates the shaft, and with a blower-fan 118, (best seen 65 in Fig. 2,) of which 117 designates the shaft, which is provided with a pulley 119, connected by a belt 120 with a pulley 121 upon the cylinder-shaft.

59 designates the fly-wheel, mounted upon the shaft 30 of the driving-engine, which latter does not appearin the drawings, but from which motion is to be transmitted to the operatin g parts of the device.

The shoe 1.22, which carries the chaffingscreen 123, is mountedifor lateral vibration by the usual means and is vibrated by the mechanism commonly employed for that purpose, which mechanism is not shown nor described herein, as the same is well understood by those skilled in the art to which my invention relates and forms no part of my present improvements. The casing 124:, in whichthe blower-fan 118 is inclosed, has its lower side inclined upwardly and rearwardly, as at 125, and adapted to direct the blast from the said fan or blower rearwardly through the shoe 1 22 and upwardly and rearwardly through and under the chatting-riddle 123. The bottom of the said casing is also formed with a trans- 9o versely-disposed conveyer-trough 126, which is below the crest 128 of the inclined bottom of the casing, whereby an eddy is formed in the said conveyer-trough,which facilitates the flowing of the grain thereinto from the inclined lower side 129 of the shoe 122. The said conveyer-trough is formedat its center with a depending discharge-spout 130. A conveyor-worm 131 is disposed and mounted for rotation in the said conveyer-trough. The I 0 said conveyer-worm comprises two reverselydisposed sections, which operate to move the grain from the ends of the trough to the center thereof to cause the same to drop through the spout 130. Caps or hoods 132 are supported over the bearings of the conveyer worm-shaft by brackets 133, which are secured to the inner sides of the said trough. The conveyer worm-shaft has a pulley 135 at one end thereof which is connected by an endless belt 136 to a pulley 137 on the shaft of the fan 118, and hence the said conveyer-worm is rotated by power communicated thereto from the shaft of said fan.

I will now describe improved means for conveying the grain from the conveyer-trough to sacks or other suitable receptacles. A conveyer-tube 138 is formed at its inner end with an upstanding elbow 139, which is revoluble on the lower end of the spout 130, so that the said conveyer maybe turned so that its outer end may be caused to project from either side of the machine, and the said conveyer-tube may be also disposed longitudinally under the center of the machine, where it will be entirely out of the way, as is shown in Fig. 2. \Vhen thus disposed, the outer end of the conveyertube may be secured, as by a chain 139 and a hook 140. At the outer end of the conveyertube is a spout 141, which is disposed at an angle to the said tube and in an inclined position to enable grain discharged thereinto from the tube 138 to flow by gravity outwardly through said spout into a sack or other receptacle. In the conveyer-tube 138 is disposed a conveying-worm 142, which is mounted for rotation, as shown in Fig. 2, and the shaft of which near its inner end is provided with a mitergear 143. The shaft 131 of the conveyor-worm 132 is provided with a miter-gear 144. A short vertically-disposed shaft 145 is journaled in a bearing 146 in the throat of the spout 130, and said shaft has a miter-gear147 at its upper end which engages the gear 144 and has a similar gear 148 at its lower end which engages the gear 143.

Hence power is communicated from the conveyer-worm 132 to the conveyor-worm 142, as will be understood, and the grain is discharged from the machine through said com *eyer-tuber 1'38 and the spout 141 thereof.

Having thus described my invention, I claim 1. In a machine of the class described, the combination of a shoe, a blower-fan, a casing for the latter having its lower side inclined upwardly to direct the blast into the shoe,a transversely-disposed conveyor-trough formed below the crest of the inclined bottom, between said crest and the shoe,and having a centrallydisposed downwardly-extending dischargespout, conveyer means for discharging the contents of the trough through said spout, and a swiveled horizontally-disposed extension connected with the lower end of the latter, substantially as set forth.

2. In a machine of the class described, the combination of a shoe, a blower-fan, a casing for the latter having its lower side inclined upwardly to direct the blast into the shoe,a transversely-disposed conveyer-trough formed below the crest of the inclined bottom, between said crest and the shoe,and having a cen trallydisposed downwardly-extending dischargespout, conveyer means for discharging the contents of the trough through said spout, a swiveled horizontally-(lisposed extension connected with the lower end of the latter,a spiral conveyer in said extension and means for transmitting motion to said spiral conveyer from the conveyor disposed in the transverse trough of the fan-casing.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

AUDY A. LOWRY.
